Notes

Inductance measured between secondary pins at 1 kHz, 0.1 Vrms, 0 Adc.
DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Volt-time product is for the secondary, between pin 2 and 4.
For specific questions regarding frequency range, please contact us at [email protected].
Primary current of 40 A causes approximately 40°C temperature rise from 25°C ambient. Higher current causes a greater temperature rise (see Temperature Rise vs Current curve).
Terminating resistance (R_T) value is based on 1 Volt output with 40 Amps flowing through the primary. Varying terminating resistance increases or decreases output Voltage/Ampere according to the following equation:
R_T= V_out × N_sec / I_in.
2100 Vrms, one minute isolation (hipot) winding to winding.

Termination:

RoHS compliant tin-silver over tin over nickel over phos bronze (pins 2-4);
RoHS compliant matte tin over nickel over copper (pins 11-12)

Packaging:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape (250 parts per full reel). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
